The example training video only provides a front view of this exercise, so it's hard to tell how much the student's legs move, but I'm pretty sure I'm bending much more than he is. Please critique and share advice on correcting this issue (if even possible at this early stage of foundations). I try keep my body upright, but once the bottom of my rib cage reaches the bar the legs tend to kick out even when I fight against it. My video includes both the strength and mobility elements. All feedback is welcome. Thanks in advance.
